Description
Die vorliegende Erfindung betrifft ein Zweikomponenten-Pastensystem zur Herstellung eines hypoallergenen Polymethylmethacrylat-freien Prothesenbasiskunststoffs.The present invention relates to a two-component paste system for producing a hypoallergenic prosthesis base plastic free of polymethyl methacrylate.
Prothesenbasiskunststoffe dienen der Herstellung der Prothesenbasis als des Teils des herausnehmbaren Zahnersatzes, der dem Prothesenlager anliegt und an dem die Zähne befestigt werden (
Es ist bekannt, Prothesenbasiskunststoffe auf der Basis einer Pulverkomponente, die als Hauptkomponente Polymethylmethacrylat-Perlpolymerisate enthält, sowie einer flüssigen Komponente, die als Hauptkomponente Methylmethacrylat enthält, herzustellen (M. Braden, R. L. Clarke, J. Nicholson, S. Parker. Polymeric Dental Materials. Springer-Verlag Berlin Heidelberg New York 1997, S. 56). In den letzten Jahren hat sich jedoch gezeigt, dass die allergischen Beschwerden im Zusammenhang mit getragenem Zahnersatz auf der Grundlage dieser Prothesenbasiskunststoffe deutlich angestiegen sind. Dabei hat sich Methylmethacrylat als Allergen nicht nur für den diesen Zahnersatz tragende Patienten, sondern insbesondere auch für den diesen Zahnersatz herstellenden Zahntechniker als nachteilig erwiesen.It is known to produce denture base plastics based on a powder component containing polymethyl methacrylate bead polymers as the main component and a liquid component containing methyl methacrylate as the main component (M. Braden, RL Clarke, J. Nicholson, S. Parker. Polymeric Dental Materials . Springer-Verlag Berlin Heidelberg New York 1997, p. 56). In recent years, however, it has been shown that allergic symptoms in connection with worn dentures based on these denture base plastics have increased significantly. Methyl methacrylate as an allergen has proven to be disadvantageous not only for the patient wearing this denture, but also in particular for the dental technician producing this denture.
Es sind nun Kunststoff-Gießmassen für die Dentaltechnik bekannt, die kein Methylmethacrylat enthalten und auf einem völlig anderen Polymersystem basieren, bestehend aus einem aus einem aliphatischen Isocyanat und einem Polyetherpolyol hergestellten Polyurethan (
Bekannt ist auch ein autopolymerisierendes Prothesen- und Unterfütterungsmaterial, enthaltend Perlpolymerisate und polymerisierbare Acrylatmonomere, bei dem keine Monomethacrylate eingesetzt werden (
Aus
Schließlich sind auch hypoallergene Dentalbasiskunststoffe bekannt, die auf monomeres Methylmethacrylat in der Formulierung verzichten, als Perlpolymerisat jedoch die Möglichkeit des Einsatzes von Polymethylmethacrylat nicht ausschließen (
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Zweikomponenten-Pastensystem zur Herstellung eines hypoallergenen Polymethylmethacrylat-freien Prothesenbasiskunststoffs zu entwickeln, bei dem die oben beschriebenen Nachteile ganz oder teilweise vermieden werden und der sich insbesondere neben dem Ausschluss von Methylmethacrylat als Monomer auch durch einen völligen Verzicht auf Polymethylmethacrylat und somit auch durch den völligen Ausschluß kleinster Spuren an Methylmethacrylatmonomer auszeichnet.The invention is therefore based on the object of developing a two-component paste system for the production of a hypoallergenic polymethyl methacrylate-free denture base plastic in which the disadvantages described above are avoided in whole or in part and which, in addition to the exclusion of methyl methacrylate as a monomer, is also achieved by completely dispensing with it based on polymethyl methacrylate and thus also characterized by the complete exclusion of the smallest traces of methyl methacrylate monomer.

The stiffness of the prosthesis base materials was characterized on unnotched specimens of the same dimensions by determining the flexural modulus E using dynamic mechanical analysis (DMA) in the temperature range from -20°C to 190°C and is given for 25°C. The results of the tests are summarized in Table 2 in comparison to those of the prosthesis base plastic obtained under the same test conditions for example 1. Table 2
